title: Random amplification of polymorphic DNA is useful for the differentiation of several anthropophilic dermatophytes.
abstract: The efficacy of random amplification of polymorphic DNA (RAPD) analysis, a polymerase chain reaction (PCR)-based technology, as a tool for differentiation of several anthropophilic dermatophytes, that is, Trichophyton mentagrophytes var. interdigitale, T. rubrum and Epidermophyton floccosum, was examined. Total cellular DNA extracted by a mini-preparation method were used as template DNAs and PCRs were performed using five primers, all of which were synthesized 10-mers. All of the primers generated PCR products and their electrophoresed profiles were characteristic for each of the species. Since these anthropophilic dermatophyte species could be differentiated clearly by the RAPD analysis, this method may be useful for identification of these species. Minimal intraspecies polymorphisms were observed between the isolates of T. mentagrophytes var. interdigitale. The banding patterns were reproducible using template DNAs prepared at different times from each of stock cultures.
